One, single arm routing
1.1.1 Introduction to single-arm routing
- 1. One-arm routing (router-on-a-stick) refers to the realization of different VLANs that are originally isolated from each other by configuring subinterfaces (or "logical interfaces", there is no real physical interface) on an interface of the router (Virtual Local Area Network) interconnection and intercommunication.
1.1.2 Advantages and disadvantages of single-arm routing
-
1. Advantages: to realize the communication between different VLANs, which helps to understand and learn VLAN principles and sub-interface concepts
-
2. Disadvantages: it is easy to become a single point of failure in the network, the configuration is slightly complicated, and it is of little practical significance
2. Case
2.2.1, requirements to achieve communication between different VLANs
2.2.2, environmental preparation
- 1. Huawei equipment used: one layer 2 switch S3700, one router, two PCs
2.2.3, configure the switch
2.2.4, configure the router
2.2.5, use the ping command to test
